Drafts, Condensation, And Comfort Problems

If you can feel moving air near the glass or frame, that is usually a sign the window is no longer sealing well.

In older homes, especially those with wood sashes or original units, these problems often start together.

When Replacement Makes More Sense Than Another Repair
